  3. 2. Fibre volume fractions’ and printing directions’ effects on tribological and mechanical properties in FDM printed carbon fibre reinforced PEEK : Suitability assessment of FDM printed PEEK-CF to act in a steam engine’s ball joint, by analysis of compressive properties, impact strength, friction and wear

    University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Author : William Tönnberg; [2022]
    Keywords : Ranotor; steam engine; PEEK; polyether-ether-ketone; carbon fibre reinforced PEEK; impact strength; compressive strength; compressive modulus; friction; wear; tribology; FFF; FDM; 3D-printing; printing parameters;

    Abstract : The purpose with this study was to investigate FDM/FFF manufactured carbon fibre reinforced PEEK and assess its suitability to act as a sealing- and bearing material in a modern steam engine’s ball joint. The steam engine is totally free from oil due to the risk of water- and steam contamination. READ MORE

  4. 3. Multibody modelling of the vibrations in an aircraft engine

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Author : Charly Mollet; [2022]
    Keywords : Vibrations; Multibody Modelling; Rolling Bearings; Rotor Dynamics; Reduction Processes; Vibrationer; multikroppsmodellering; rullingslager; rotordynamik; reducktionsprocesser;

    Abstract : During the assembly of aircraft engines, some clearance is left in the rolling bearings mainly to reduce friction. However this clearance might allow the rolling element to vibrate during flight. Indeed, unwanted vibrations called non-synchronous vibrations (NSV) appear on the data recorded by the sensors on some development engines. READ MORE

  5. 4. Virtual verification and improvement of innovative wind turbine gearbox design

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Ioannis Pierratos; [2021]
    Keywords : Gearbox; Multibody Dynamics; Wind Turbine; Multikroppsdynamik MBS ; Vindkraftverk; Växellåda;

    Abstract : Cascade Drives develops electromechanical linear actuators based on multiple pinions interacting with a gear rack. With a patented load sharing mechanism, that uses flexible torsional elements, the torque is equally distributed among the pinions. READ MORE

  6. 5. Dynamic Analysis of an Automotive Power Transfer unit : Towards prediction of TE and housing vibrations

    University essay from KTH/Maskinkonstruktion (Avd.)

    Author : Nikhil Maharshi Kosaraju; [2019]
    Keywords : Power transfer unit PTU ; Multi-Body Simulation MBS ; Transmission Error; Gear NoiseVibration; Modal Analysis; Vinkelväxlen PTU ; Multi-Body Simulering MBS ; transmissionsfel TE ; Växelljud och vibrationer; Modal analys;

    Abstract : This work describes the use of Multi-Body Simulation (MBS) to create a virtual prototype of a geared drive called Power transfer unit (PTU). PTU is a subsystem of the all-wheel drive driveline responsible for transfer of power between front and rear axles in an Automobile. READ MORE
